Automatic Restart - Salicru SLC ADAPT2 Series User Manual

Removing a faulty module.
It is not necessary to switch the device to "Bypass Mode",
•
since power modules can be removed while the system is
in operation. We recommend that you check that the load
power does not exceed the power of the remaining func-
tional modules.
Stopping a module: To stop a power module, the operation
•
must first be enabled via the display in the "Status&Op"
menu, and then the module can be stopped by pressing the
button and the "On/Off" button next to the LED
indicators on the display simultaneously during 1 minute. To
do this, use an object of diameter ≤ 3 mm, such as a small
screwdriver, inserted into the hole indicated as " " and press
the button located on the inside for around 5-6 seconds.
Wait about 10 minutes for the condenser group on the
•
module's internal DC bus to discharge completely before
removing the module.
Maintenance operations are restricted to
sonnel or the distributor. Under no circumstances can
there be any access to the inside of the equipment, apart from
the connection operations, which are also reserved exclusively
for qualified personnel.
Do not open the sub rack or modules, there is a high risk
of an electric shock that could be fatal.
When the UPS is operating in "Manual Bypass Mode"
(maintenance or repair period), the connected equip-
ment is not protected against power cuts or micro-cuts, over-
voltages, voltage and/or frequency variations, etc., since it is
being supplied directly from the commercial AC mains.
6.3.2. Procedure to switch from maintenance bypass mode
to normal mode.
1.
Reset all the modules of the system when they have been
extracted as indicated in point 2 of the section 6.3.1, above.
Insert and secure them.
2.
Activate the circuit breakers of the manual bypass board
in the following order: Bypass [device version B, with inde-
pendent bypass line], Input and Output.
The LCD touch screen starts up. The rectifier indicator
flashes during start-up. The rectifier enters the normal
operating state and after around 20 seconds the rectifier
indicator stops flashing red to remain permanently active in
green. After initialisation, the static bypass remains active,
supplying voltage to the output terminals from the AC main;
the bypass indicator turns green. Check this last point on
the display and/or the LCD screen before proceeding.
3.
Turn the manual bypass switch on the external panel to
"Off" and set the mechanical lock.
In installations with protection boards [without manual
bypass switch], turn the manual bypass switch on the sub-
rack to "Off" and place its mechanical lock.
For safety, it is necessary to block the switch me-
chanically, otherwise there is a risk of unexpected
operation of the switch at any time, with the consequent
destruction of the UPS and the load.
4.
After around 60 seconds, the UPS transfers the load to the
inverter. Switch the protection or the battery circuit breaker
of the battery cabinet to the "On" position.

6.4. EPO PUSH BUTTON (EMERGENCY STOP). PROCEDURE.
Conceptually the EPO push button is designed to disconnect the
UPS in emergency conditions (e.g. fire, flood, etc.).
The device has an EPO push button and the user can install
an external one, connected to the device via communications
terminal J4.
When the EPO button is pressed, the system immediately
stops the rectifier, the inverter and the bypass, leaving the load
without power. Batteries are no longer charged or discharged.
If the AC input network is present, the UPS control circuit will
remain active, but without voltage at the output.
To completely isolate the UPS, follow the steps in the next sec-
tion.
6.4.1. Complete stop of the UPS, with EPO.
1.
If stopping is planned or scheduled, stop the loads before-
T.S.S. per-
hand. In case of emergency, go directly to step 2.
2.
Press the EPO button on the bypass and monitoring module.
3.
Switch the protection or the battery circuit breaker of the
battery cabinet to the "Off" position.
4.
Switch the circuit breakers of the manual bypass board to
the "Off" position in the following order: Bypass [device
version B, with independent bypass line], Input and Output.
The EPO condition will be clear when the input
panel switch to "Off" is pressed.
The UPS is completely out of service.
6.4.2. UPS restart after full stop with EPO.
The procedure is used to restore the system after the EPO has
been activated and its complete stop:
1.
Once you press the EPO button, you need to end the proce-
dure before attempting to restart the system.
2.
Restart the UPS as described in section 6.2.2.
The alarm will be cancelled, so the EPO status will
be deleted when the input off operation described in
the preceding paragraph is executed.

6.5. AUTOMATIC RESTART.

When the UPS is operating in Normal Mode and the input mains
fails, it will automatically switch to Batteries Mode, where the
loads are fed from the inverter from the energy stored in the
accumulators. If the mains failure goes on beyond the possible
power that the battery pack can supply, the end of discharge is
reached and the UPS will stop.
The UPS will restart automatically by supplying output voltage:
1.
After returning the commercial AC network.
2.
If the parameter "Automatic reset" after EOD is enabled.
